How to Put a Ghost Immobiliser Into Service Mode

When should you use service mode?

Use it whenever someone else needs to drive the car and you would rather not share your disarm code. Typical moments are a service or MOT, a repair, a hand car wash, a valet, or an airport parking desk. Your code stays private and nobody has to wait for you to start the car.

Step by step

1. Disarm the Ghost with your sequence, or with the app if you use one. The indicator flashes twice.
2. Start the engine and leave it running.
3. Press the service button five times. It is one of the buttons chosen when your Ghost was set up, so check your handover notes if you are not sure which one it is.
4. Watch for five flashes. That tells you service mode is active.
5. Hand over the keys. The garage needs nothing else from you.

If the Ghost app has been paired with your phone, you can also turn service mode on and off from the app.

How does service mode switch off?

There are two ways. The first is to enter your disarm sequence once the car has been switched off and on again. Two flashes confirm it, and full protection is back straight away. The second happens without you: Autowatch states that the Ghost leaves service mode once the car has been driven at 32 mph (50 km/h) for more than 15 minutes, and the 15 minutes can be adjusted when the Ghost is installed. That is a safety net in case you forget. It also means a long road test can end service mode early, so do not be surprised if the car asks for your code when you collect it.

Is the car protected while it is in service mode?

No. In service mode the Ghost does not ask for a code, so anyone holding the key can start and drive the car. Only leave it on while the car is with someone you trust, and switch it off as soon as you have the car back.

Ghost-II and Ghost 3

Both models use service mode in the same way, following Autowatch’s published steps. If your Ghost 3 was fitted by us and the sequence does not work, call us on 0800 246 1482 and we will talk you through your own setup.

What if it will not go into service mode?

• No two flashes after your code: the sequence was not accepted. Pause for a few seconds and enter it again, slowly.
• Two flashes but no five flashes: you are probably pressing a different button. The service button was set at installation.
• You have forgotten your code: this is the most common reason customers call us. Do not keep guessing. Every Ghost-II comes with its own emergency code, which lets you disarm the car and set a new sequence. If you cannot find it, contact us.
